To all whom t may concern.'

Be it known that I, Louis ViLrU'r'rE, a citizen of the United States,and resident of New Rochelle, in the county Ot Vestchester and State ofNew York, have invented certain new and useful Improvements inRegenerative Coke-Ovens, of which the tollowing is a specification.

My present invention relates to the type of regenerative coke ovenshaving horizontal coking chambers separated by intervening heating wallsformed each, with a series of vertical flues connected in pairs at theirupper ends; and thegeneral object of my invention is to provide animproved arrangement of the regenerators and regenerator connections forsupplying preheated air alternately to the two lues of each connectedpair.

2O The various features of novelty which characterize my invention arepointed out with particularity in the claims annexed to and forming apart of this specification. For a better understanding oi the inventionand the advantageous features possessed by it, reference should be hadto the accompanying drawings and descriptive matter, in which I haveillustrated and described preferred embodiments of my invention.

i Of the drawings:

Figure l is an elevation in section on the broken line 1-1 of Fig. 5.

Fig. 2 is a partial plan in section on the line 22 of Fig. l. Fig. 3 isan elevation in section on the broken line 3-3 of Fig. l.

Fig. 4; is a partial elevation in section on the line 4-4 of Fig. l.

Fig. 5 is a partial plan in section on the line of Fig. l; andV Fig. 6is a view taken similarto Fig. 5 illustrating a modiied construction.

In the drawings, and referring first to the construction shown in Figs.le inclusive, the coke oven shown, comprises a plurality of horizontallyelongated coking chambers A., separated by heating walls, each of whichis divided into a series of lues B and l). As shown in'Fig. 3, each flueB is separated from the adjacent flue l) at its right by a wall B10whichterminates at its upper end below the tops of the flues B and L, sothat the pair ot' lines B and o between which each wall B10 is located,are connected at their upper ends. Each pair of lues B, Z), thusconnected at their upper ends, is separated trom adjacent pairs of uesB, b by a wall B11.

Each heating wall is carriedby a supporting or pillar wall C. Below thecoking chambers and between the pillar walls C, are series or row's oitregenerator chambers E and c. The chambers Il or e in each row areseparated from one another by division walls B10 or (210 lying` in thesame plane as 65 the flue division walls B10 and B11. The regeneratorchambers E alternate with the regenerator chambers e in a direction'transverse to the lengths of the heating walls. The row of regeneratorchambers E between one adjacent pair of pillar walls C are connected tothe lues B in the two heating walls above the pillar walls C by channelsor ports II. Similarly the row of regenerator chambers e between anadjacent pair of pillar walls C are connected by ports 7L to the fiues2') in the two heating walls above these pillar walls. It will beunderstood that each of the regenerator chambers E and e is connected toa flue B or b lying between the division walls B10 and B11 which areimmediately above the side walls B10 or 61 of the correspondingregenerator spaces E or e.

As shown in the drawings, there are a series orf regenerator chambers eaat one end of the battery connected by ports 7L to the tlues Y) in theone adjacent heating wall; and at the other end of the battery there area series of regenerator spaces EA connected by ports II to the lines Bin the one adjacent heating wall. The regenerator chambers EA and caditer from the chambers E and e in that there are but half as many ofthese in a row, and in that each of the regenerator chambers EA and @ais conveniently made twice as wide, measured parallel to the length ofthe oven chambers and heating walls, as a regenerator chamber E or e. Itwill be understood, of course, that the checker brick (not shown) ispiled in the usual manner in the different regenerator chambers E and e.

Beneath each row of regenerator spaces E and EA are located channels orconduits F and G. Eachv channel F preferably receives an iron air supplypipe FA formed with discharge oriiices which register with the brickworkports F, opening into the lower end of the corresponding row of re-`channel G which serves as a waste heat channel is connected to each ofthe regenerator spaces above it by a corresponding port G. All of thewaste heat channels are connected, each through a corresponding valvecasing D10 to a tunnel D running transversely to the length of thecoking` chambers at one side ot the battery, and as shown the outer endot each air pipe FA is connected to the corresponding valve casing' D10through a. port F2 in the latter. A valve member D11 is mounted in eachvalve czsing D10 between the port F2 and the corresponding channel G.These valve members D11 areconnected to the usual rc- Versing' mechanism(not shown) and serve, when in their closed positions, to cut offcommunication between the waste heatchannels G and the tunnel D.Advantageously the valve members D11 are provided with portions D12closing the corresponding ports F2 when the valve members D11 are movedto permit comxnuiiication between the channels nl and the tunnel D.Similarly, beneath each row oi regenerator chambers c and ea is locateda pair of channels f and g which connect by corresponding` ports and gto the regenerator chambers above them. The channels g are connectedbyvalve casings d10 to a tunnel cl, running lengthwise of the battery atthe opposite side ol the latter from the tunnel D. The channels fpreferablyv receive iron air'supply pipes fa, similar to the air pipesFA and connected to the valve connections f 1 as the air pipes FA areconnected to the valve casings D10; and in each valve casing (ZW ismounted a Valve member D"1 similar in construction and operation to thevalve member D11 in each Valve casing` D10. D13 and Z13 represent draftregulating` dampers in the valve casinfgfs D1 and Z111 respectively.

rldrantageously the channels (l and g are' tapered in the direction oi'their lengths to insure an approximately uniform How velocity ot' thewaste gases through the channels G andv y at" all points along; thelengths of the channels. The ports G and g aswell as the dischargeorifices in the iron air pipes FA and fa. are proportioned to insure thedesired distribution of low among' theV different heatingn fines andregenerator spaces.

Combustible gras is supplied, when re` quired, to the lower end ot eachi'iue B through a port I1 and the usual removable gas nozzle thereinfromv a corresponding gas gun or gas supply passage lf', therebei'n'g'one of these supply channels l in the upperportion ofeachpillar' wall'C. Similarrly each'lue 7;' receives'comlmstib'le gas at theproperV times through a corresponding port i' and the usual removablegas nozzle froma gas gunJ or chan-nelz'f 'located inthe upper' portionof the corresponding` pillar wall C.

ln the arrangement shown in Figs. l and 5 all the gas guns l and t" areconnected through corresponding valved connections, one of which, markedi2, is shown in Fig. 3, to a gas supply main In located at one side ofthe battery. ln the construction partially shown in Fig 6, the gas gunsl all project at one side ot the battery and are connected to a gas mainat that side of the battery, while the gas guns z" project from theopposite side oi the battery and are connected to a gas main lying atthat (opposite) side of the battery. rllhe `different arrangements oith'egas guns shown in Figs. 5 and 6,result in certain difference in' thearrangement of ports l and in construetions shown in Figs. 5 and 6.TheseA arrangements are clearly shown, and will be readily understood bythose skilled in the art, from the drawings and need not be described infurther detail.

lAir and gas are suppliedto the lower ends ot allot the Various [lues Bduring one period or stage of operation, while during the followingstage of operation air and combustible gas are supplied to the lowerends of all the fines The vahfesDm and d10, the Valves controlling thesupply of gas to the gas guns l and t, and the valves (not shown)controlling communication between the tunnels D and (Z and air blower orfan, and a stack or other suction creating device being' manipulated inthe usual way to bring;V about a reversal ot flow at the usual intervalsof, say one-halt hour each.

In the condition of the apparatus shown in the drawings air and gas arebeingsupplied to the lower ends of the fines B. The tunnel D is thendisconnected' from the stack, and receives air from ay fan or blower,While the tunnelti is disconnected from the source of air supply and isconnectedfto astack or other draft suction creating device. The ValvesD11 in the Valve casings D10 are set to close communication between thetunnel D and the waste heat channels G and to permit air to pass 'fromVtunnel D through ports F2 into the air' supply pipes FA; In thiscondition ot the apparatus the valve members D11 in the Valve casings0310 are in the position in which they open communication between thewaste heat channels g and tunnel (Z, and in'which they closecommunication between tunnel d' and the air pipes fa. Thel air thuspermitted to pass into the air supply pipes FA is discharged from thelatterthro'ughthe ports F into the lower ends of the various regeneratorchambers E and EA.l The air passes upward through the regeneratorchambers E and 'EA and is thereby heated. The heated air passes out ofthe chambers E and ea into the fines B-through the ports H. Thepreheated' air loro thus entering the lower ends of the liue B ignitesthe combustible gas then being supplied to the lower ends of the iue Bthrough the ports I from the gas guns I which then receive their gasfrom the corresponding external gas supply main. In this condition ofoperation the gas guns z" are disconnected from the gas supply main. Theburning ases ignited at the lower ends of the flue pass upward throughthe latter, thence over the tops of the iue walls B10 into the flues b,following downward through the latter and out through the ports. 7L. Thehot products of combustion leaving the lines through the ports 71 enterthe regenerator chambers e and @a and after imparting a large portion oftheir heat to the checker brick in those regenerator chambers issue fromthe latter. through the ports g into the channels g, through which theypass to the valve casing d10 and through the latter into the tunnel d.

It will be apparent from the previous description of the apparatus, aswell as from the arrows on Figs. 5 and 6 that each row of regeneratorchambers E between an adjacent pair of pillar walls supplies preheatedair to the lues B in the two heating walls at each side of the row ofregenerators, while each row of regenerators e receive the products ofcombustion from the flues Z9 of the two heating walls at the oppositesides of the row of regenerators e. lmien the direction of the flow isreversed, air is supplied from the tunnelV d to the air supply pipes fa,passes from the latter to the regenerator chambers c and ca, ispre-heated therein, and passes out of these chambers through the portsit into the iues b, while combustible gas is then supplied to the lowerends of the iues b by the gas guns i.. The burning gases ignited at thelower ends of the flues b then pass upward through the latter, downwardthrough the lues B, and from the latter through the Y ort's H to theregenerator chambers and A and out of the latter through the ports G,channels G and valves D10 into the tunnel D.

Since each of the flues B and b is connected to but one regeneratorchamber, it is only necessary to insure the proper supply of air to eachon regenerator chamber, and the proper supply of gas to the lower end ofthe flue to which each on regenerator chamber is connected to insure theproper distribution of flow among all the iues and regenerator chambers.The supply of combustible gas may be regulated in the usual manner bythe use of interchangable nozzles of proper size, and the supply of airto the reGenerators is primarily regulated by the sizes of the dischargeorifices in the iron air supply pipes FA and fa. When a change in thedistribution of air is desired these iron air supply pipes may be with-7drawn and the discharge orifices restricted orv enlarged as required. Toavoid undesirable pressure diiierences in the various flues andpassages,`the olf-take channels Gr and g are preferably tapered, aspreviously described, and the ports G and g should be properlyproportioned. In addition to the simplicity and positive control, of thedis tribution of air and gases, obtained with the present invention itis to be observed that the oven and regenerator construction is simpleand compact, and that the oven brickwork may be constructed inaccordance with accepted and tested principles of design andconstruction.

While in accordance with the provisions of the statutes I haveillustrated and described the best forms of my invention now known tome, it will be apparent to those skilled in the art that changes may bemade in the form of the apparatus disclosed without departing from thespirit of my invention as set forth in the appended claims, and thatcertain features of the invention may sometimes be used to advantagewithout a corresponding use of other features.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent, is:

l. In a coke oven comprising horizontal coking chambers, interveningheating walls divided into vertical fines connected in pairs at theirupper ends and provision for periodically supplying gas to the lower endof one flue of each pair, and at alternate periods to the lower ends ofthe other flues, the improvement which consists in a separateregenerator chamber connected to the lower end of each flue.
